[0030] Based on the above technical solution: Through the above arrangement, when using the fat-shaking mode, the user steps on the running belt with both feet and is located above the two pedal parts respectively. The two pedal parts can smoothly pass through the relief hole and vibrate up and down alternately; when using the running mode, the two pedal parts cooperate with the running board to support the running belt.

[0031] The beneficial effects of the present invention are as follows:

[0032] By providing a running component and a fat-shaking component on the chassis, the present invention has a running function and a vibration fat-shaking function. When using the running function, the driving component drives the main roller to rotate through the first transmission component, so that the main roller drives the running belt and the slave roller to rotate; when using the fat-shaking function, the driving component drives the two pedal parts on the vibration frame to move up and down alternately through the second transmission component to achieve vibration fat-shaking.

The drive assembly 2 further includes a drive motor 21, a fifth pulley 22 coaxially arranged with the first transmission shaft 23, and a third transmission belt 24 arranged between the output shaft of the drive motor 21 and the fifth pulley 22. The first transmission shaft 23 is rotatably connected to the chassis 1.

[0055] The switching assembly 5 includes a transmission seat 51 that is synchronously and rotatably connected to the first transmission shaft 23 and can slide left and right relative to the first transmission shaft 23. The transmission seat 51 is located between the input end of the first transmission assembly 6 and the input end of the second transmission assembly 7, and the transmission seat 51 includes a first position in transmission connection with the input end of the first transmission assembly 6 and a second position in transmission connection with the input end of the second transmission assembly 7. By driving the transmission seat 51 to slide along the first transmission shaft 23, the transmission seat 51 can be switched between the first position and the second position.

[0056] Among them, in order to make the operation safer, the transmission seat 51 further includes a third position between the first position and the second position; when the transmission seat 51 is in the third position, the transmission seat 51 is disengaged from both the first transmission assembly 6 and the second transmission assembly 7, that is, the third position is a neutral position.

[0057] In some specific embodiments, such as Figures 1 to 6 and Figure 9As shown, a first engaging tooth 611 is provided at the input end of the first transmission assembly 6, and a second engaging tooth 711 is provided at the input end of the second transmission assembly 7.

The shape of the fork 521 is preferably arc-shaped or C-shaped and can rotate relative to the sleeve 513, so that when the transmission seat 51 rotates, it will not drive the lever handle 52 to rotate. Alternatively, the fork 521 can also be provided with a structure detachably connected to the transmission seat 51, so that the lever handle 52 can be detached after adjustment without affecting the rotation of the transmission seat 51.

[0060] In some specific embodiments, such as Figures 1 to 6 and Figure 9 As shown, the first transmission assembly 6 includes a first pulley 61 coaxially arranged with the first transmission shaft 23, a second pulley 62 coaxially arranged with the main drum assembly 41, and a first transmission belt 63 located between the first pulley 61 and the second pulley 62; a first bearing 516 is provided between the first pulley 61 and the first transmission shaft 23; the first engaging tooth 611 is provided on the side of the first pulley 61 close to the transmission seat 51, that is, when the transmission seat 51 is not connected to the first pulley 61, the first transmission shaft 23 will not drive the first pulley 61 to rotate;

[0061] And / or, the second transmission assembly 7 includes a third pulley 71 coaxially arranged with the first transmission shaft 23, a first rotating shaft 74 rotatably arranged on the chassis 1, a fourth pulley 72 coaxially arranged on the first rotating shaft 74, and a second transmission belt 73 located between the third pulley 71 and the fourth pulley 72; a second bearing 517 is provided between the third pulley 71 and the first transmission shaft 23. The second engaging teeth 711 are arranged on the side of the second pulley 62 close to the transmission seat 51, that is, when the transmission seat 51 is not connected to the second pulley 62, the first transmission shaft 23 will not drive the second pulley 62 to rotate.

[0062] In some specific embodiments, the first transmission shaft 23 and the transmission seat 51 are synchronously rotationally connected through a spline, and the structure of the spline is arranged such that the transmission seat 51 can slide relative to the first transmission shaft 23.

[0063] In some specific embodiments, as Figures 6 to 8 shown, the middle part of the vibrating frame 31 is hinged to the chassis 1, and an eccentric vibration assembly 8 is provided between the output end of the second transmission assembly 7 and the vibrating frame 31; the eccentric vibration assembly 8 includes an eccentric wheel 81 connected to the output end of the second transmission assembly 7 and a vibration seat 82 arranged on the eccentric wheel 81. The lower end of the vibration seat 82 is sleeved on the eccentric wheel 81, and the upper end of the vibration seat 82 is rotatably connected to the lower side of one of the foot pedals 311 on the vibrating frame 31. Specifically, the middle part of the vibrating frame 31 is hinged to the chassis 1 through a hinge seat 312, a fixing frame 313 is provided between the upper end of the vibration seat 82 and the vibrating frame 31, the fixing frame 313 is fixedly connected to the side of the vibrating frame 31 close to the main roller assembly 41, and the upper end of the vibration seat 82 is rotatably connected to the fixing frame 313 through a second rotating shaft 83.

[0064] In some specific embodiments, as Figures 1 to 6 and Figure 9As shown, the main roller assembly 41 includes a main shaft 411 fixedly arranged on the chassis 1 and a main roller 412 rotatably arranged on the main shaft 411. The secondary roller assembly 42 includes a secondary shaft 421 rotatably arranged on the chassis 1 and a secondary roller 422 rotatably arranged on the secondary shaft 421. A bolt 44 is provided between the driven shaft and the chassis 1, and a bolt hole 44 for the bolt 44 to pass through is provided on the chassis 1. The threaded section of the bolt 44 is threadedly connected to the driven shaft. By rotating the bolt 44, the secondary roller assembly 42 can move towards or away from the main roller assembly 41. Specifically, there are two bolts 44, respectively located on the left and right sides of the secondary shaft 421. When used in the running mode, the running belt 43 can be tensioned. When used in the fat-burning mode, the running belt 43 can be appropriately relaxed to facilitate the alternating up and down vibration of the two footrest parts 311 on the vibration frame 31.

[0065] In some specific embodiments, as Figures 6 to 8 shown, a relief hole 451 is provided in the middle of the running board 45. The vibration frame 31 is located between the upper and lower layers of the running belt 43, and both of the two footrest parts 311 are arranged at the relief hole 451. The footrest part 311 is specifically a pedal fixedly arranged on the vibration frame 31. The two footrest parts 311 are integrally formed. By providing the relief hole 451, in the fat-burning mode, the two footrest parts 311 of the vibration frame 31 can alternately vibrate up and down and be transmitted to the human body through the running belt 43.

[0066] In some specific embodiments, when used in the fat-burning mode, the two ends of the vibration frame 31 alternately move up and down. After the fat-burning mode ends, the situation where the vibration frame 31 does not return to its position may occur, that is, the footrest part 311 is not parallel to the running board 45. At this time, it is possible that the footrest part 311 abuts against the running belt 43, affecting the operation of the running belt 43. To avoid the above problems in this embodiment, a position detector for detecting the position of the vibration frame 31 is further provided on the chassis 1. Specifically, when switching from the fat-burning mode to the running mode, if the vibration frame 31 does not return to its position, the position detector can give an alarm to remind the user.

[0067] Working principle description:

[0068] When using the running mode, the user switches the output end of the drive assembly 2 to be connected to the input end of the first transmission assembly 6 by pulling the drive seat 51, so that the drive assembly 2 drives the running assembly to operate through the first transmission assembly 6. When using the fat-burning mode, the user switches the output end of the drive assembly 2 to be connected to the input end of the second transmission assembly 7 by pulling the drive seat 51. Then the user's feet step on the two footrest parts 311 respectively, and the drive assembly 2 drives the two footrest parts 311 to swing alternately up and down through the second transmission assembly 7.

[0069] The present invention is not limited to the above optional embodiments. On the premise of not conflicting with each other, the various solutions can be arbitrarily combined; anyone can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they all fall within the protection scope of the present invention.
